The cottonseed meals reported in this bulletin 

 Cottonseed and represent with few exceptions the crop of 1907. 

 Linseed Meals. As much more cottonseed is found on the market 



Pages 8-1 1. during the winter and spring than during the fall 



months, the cottonseed meals taken during the 

 winter collection are reported together with those of the recent fall 

 collection. Much of the 1906 meal, on account of adverse weather 

 conditions was inferior and 75 per cent of the samples collected 

 failed to maintain their nitrogen and protein guarantees. The 1907 

 crop has shown a decided improvement and of 44 samples here 

 reported only 22 per cent have fallen below their guarantees and 

 these but slightly. The Inter-State Cotton Crushers' Association 

 grades cottonseed meal as follows : (Rules as amended and adopted 

 May 18, 19, 20, 190S.) 



" Choice cottonseed meal xnwsX. be finely ground, perfectly sound and 

 sweet in odor, yellow, free from excess of lint and by analysis must 

 contain at least eight per cent of ammonia, or forty-nine per cent of 

 combined protein and fat. 



Priine cottonseed meal must be finely ground, of sweet odor, reason- 

 ably bright in color, yellow, not brown or reddish, free from excess of 

 lint, and by analysis must contain at least seven and one-half per 

 cent of ammonia or forty-six per cent of combined protein and fat.

 ably bright in color and by analysis must contain at least seven per 

 cent of ammonia, or forty-three per cent of combined protein and 

 fat." 



According to this classification choice cottonseed meal must contain 

 at least 8 per cent of ammonia which is equivalent to 6.56 per cent 

 of nitrogen or 41 per cent of protein. Prime cottonseed meal must 

 contain at least 7.5 per cent ammonia which is equivalent to 6.17 

 per cent nitrogen or 38.57 per cent protein. Good cottonseed meal 

 must contain 7 per cent of ammonia which is equivalent to 5.75 per 

 cent of nitrogen or 36 per cent protein. According to the above 

 rules a meal which, through faulty extraction or for some other rea- 

 son, contained less than 41 per cent protein could be classed as
